Does anyone have any experience with the ISR mounts for an RB25 into an S13? I'm currently running a R33 sub-frame with hockey pucks but it sits pretty high and the shifter is a little too far forward. I also have an S13 sub-frame so I was looking at the ISR mounts but I'm open to other suggestions as well.

I'm running the ISR mounts with my RB25 swap. They sit the motor fairly low and I don't have any hood clearance issues running the factory intake manifold. I'm running a RB20 transmission so I'm not sure about placement with the 25 trans, but my shifter sits in the factory location. You'll definitely want to run a skidplate with the ISR mounts though since they sit the oil pan a bit below the crossmember.

Quality wise they're ok. I like the design and they seem pretty well made, but I did have to do some minor modification to get everything to bolt up properly. The poly bushings feel pretty solid and the motor doesn't move, but they don't seem to vibrate anymore than my old rubber mounts. Overall I'm happy and would probably buy them again.

Awesome, that's exactly what I wanted to know. Seems like it'll be a good fit then.
